Subject: 23.0.92; detaching GTK+ tool bar crashes emacs --daemon
Date: Tue, 28 Apr 2009 16:41:00 +0200

(This is my fourth attempt to get this into the bugtracker.  On the hope
that there was something about the email body and not my address that
was objectionable, I am omitting the backtrace now.  If this email gets
through, I'll try following up with the backtrace.  Whether or not that
succeeds, the backtrace is available at
<http://lists.gnu.org/archive/html/emacs-devel/2009-04/msg00496.html>
and <http://permalink.gmane.org/gmane.emacs.devel/110453>.)

Carrying out the following steps reliably crashes Emacs:

1. emacs -Q --daemon
2. emacsclient -c
3. Detach the tool bar (only possible with GTK+ build).
4. Close the client frame with C-x 5 0
5. emacsclient -c
6. Detach the tool bar
=> SIGSEGV

If I do not start with --daemon or if I skip either step 3 or step 4,
there is no crash.

Actually, daemon mode is not needed.  You can also do this:

1. emacs -Q -nw
2. M-x make-frame-on-display RET :0.0 RET
3. Detach the tool bar
4. Close the client frame with C-x 5 0
5. M-x make-frame-on-display RET :0.0 RET
6. Detach the tool bar
=> SIGSEGV

Jan, could you try to debug this?  It may be another manifestation of
the problems we've been having with GTK and closing X connections.

It looks like it.  The window for the detached tool bar is created and managed 
by Gtk+ and is not deleted when the display is removed it seems.

I'll see if we can work around it.

Sorry, no workaround is possible.
The part in Gtk+ that handles detaching uses a hidden window which it stores 
in a static variable.  So it get created on the first display, but is still 
used on the second, but that is not a valid window anymore:

static GtkWidget *
gtk_handle_box_get_invisible (void)
{
  static GtkWidget *handle_box_invisible = NULL;

  if (!handle_box_invisible)
    {
      handle_box_invisible = gtk_invisible_new ();
      gtk_widget_show (handle_box_invisible);
    }

  return handle_box_invisible;
}

This is another instance of the "there is just one display and it is always 
open"-mindset of Gtk+.

I have filed a Gtk+ bug on this 
(http://bugzilla.gnome.org/show_bug.cgi?id=581110). Not sure what we should do 
about this bug though.  Keep it until Gtk+ fixes/rejects the bug report or 
close it?

No harm keeping the bug open, I think.  Thanks for investigating.

As long as this does not change in GTK+ and no workaround is possible in
Emacs, I (sadly) think you should seriously consider disabling detaching
the tool bar in the GTK+ build.  When used in conjunction with --daemon
it is a ticking time bomb for data loss because of the crash it causes.
I don't make this suggestion lightly, since detaching the tool bar is to
me an acceptable workaround for the very annoying shrinking frame bug
(see bug#3195), but precluding a crash and possible data loss should
probably take precedence over avoiding annoyance.

I don't mind disabling detaching if it is OK in the current code freeze.

IMHO detaching the toolbar is a red herring here.

Yes, there on big valid reason to disable detaching the toolbar: it
seems that detaching the toolbar is disabled by default by (almost?) all
Gtk+ applications.

The ticking time bomb is actually using an emacs compiled with the Gtk+
support in conjunction with multi-tty.  emacsclient + kill emacsclient +
emacsclient results in a crash.

IMO we need at least a big fat warning in NEWS (or some other very prominent
place) with a reference to the Gtk+ bug to make users aware of the
problem.  We've had many bug reports about this, we'll only get more
after the release.

We have an entry in PROBLEMS, which may need to be updated.  I have no
objection to adding a warning to NEWS as well.  Could someone try to
summarize, as well as you can, the circumstances that are likely to lead
to lead to a crash?

It would be useful to make Emacs detect this case and give a clean
error message such as "Due to GTK+ bug number XYZ, what you want to do
is impossible", rather than just crashing.

The good news is that the bug has been marked as FIXED.  But I don't know in 
which Gtk+ version the fix will appear in.  The only way to detect this 
particular bug is by checking version numbers.

This is included in GTK+ 2.16.2, but the recipe to crash Emacs from the
original report still works in
GNU Emacs 23.1.50.4 (x86_64-unknown-linux-gnu, GTK+ Version 2.16.5)
of 2009-08-04 on turtle .

Note that this recipe does not even involve multiple displays.

You are correct, the fix in Gtk+ is no good, it is obvious that they didn't 
test the fix.
I've reopened the Gtk+ bug for this with new information:
http://bugzilla.gnome.org/show_bug.cgi?id=581110


Hopefully a better fix will come.

This bug remains with "severity: critical" and no fix in the gtk bug
tracker.  So perhaps Emacs should do a workaround anyway?

The only workaround that works is not having detachable toolbars.
I'm not opposed to that. Detachable toolbars is on its way out from Gtk+ anyway. I'm surprised they are in Gtk+ 3.0.

The Gtk+ bug is now marked "resolved obsolete" as the widget is
deprecated. Does anyone know if it was ever fixed or if it's even still
an issue? (I don't have a Gtk+ set-up to test on.)

With GNU Emacs 24.3.1 (x86_64-suse-linux-gnu, GTK+ Version 3.14.2) of
2014-10-15 on build05 I do not get a crash by executing either of the
two recipes given in this bug thread, so I assume it was either fixed
somewhere or maybe it was only a bug with GTK2 (that's what I was using
when I reported the bug, but I cannot currently test that).  Moreover,
it's a nonissue for Emacs 25, since there the GTK+ tool bar is no longer
detachable.  So I think this bug can be closed.
